Testimonials

AkerBP

"Aker BP has used "Diving Advisors" as Client Dive Representatives offshore since 2016. The staff of advisors that we have used delivers to the standard we demand year after year. It is particularly good to see that we are also getting "younger" forces to our industry who will be able to take over the helm in time. Aker BP is extremely satisfied with the quality and competence of "our" advisors delivered through NUI Advisory Services"
